Viruses, Worms, & Malware

What can malware do to my computer?

Malware, short for "malicious software," includes
a wide variety of bad software including adware, spyware, hijackers,
worms, Trojan horses, and viruses which can all wreak havoc on your
computer. It can damage or destroy data on your computer. Malware
can also hijack your browser, redirect your online searches, and
even track your online browsing. Back doors can open up your personal
computer to anyone on the Internet. Not only can worms disrupt your
own system, they can replicate themselves on the systems of people
you are in regular email contact with. Malware can also make your
computer become excruciatingly slow and/or unstable.

How can I protect my computer from malware?

Never accept software downloads from strangers.

Never open unexpected email attachments--verify them first by calling
the sender.

Be sure to install the latest anti-virus software and use and
update it regularly. University IT has negotiated a volume license for Sophos Anti-virus
software. Be aware, though, that all virus scanners have limitations,
and that virus-writing techniques are evolving continually.

There are no guarantees to protecting your computer from malware. Anti-virus software is an important tool to
use, but it is no substitute for common sense. If you don’t update virus definition files regularly (weekly,
at least) and scan regularly (the whole drive, including “Recycle”
and “Trash” bins, not just system areas), then you may be
hit with a virus or other software that is destructive and/or compromising.
